Scope

This document defines the procedure of NFP (near field pattern) analysis of a multimode optical waveguide with rectangular core(s) with use of EF (encircled flux) analysis methodology. Circular optical fibres are out of the scope of this document.

Optical waveguides that can be connected to graded index multimode fibres (e.g. OM3, A4i, etc.) are applicable.

Purpose

Bandwidth densities in modern data communication systems are driven by interconnect speeds and scalable input/output (I/O) and will continue to increase over the coming years, thereby severely impacting cost and performance in future data communication systems, bringing increased demands in terms of signal integrity and power consumption.

The projected increase in capacity, processing power and bandwidth density in future information communication systems will need to be addressed by the migration of embedded optical interconnects into system enclosures. In particular, this would necessitate the deployment of optical circuit board technologies on some or all key system cards, such as the backplane, motherboard, and peripheral circuit boards.
